So the movie's flawed. So it leaves us with loose ends and questions. That finally doesn't bother me, because what it does accomplish is done so well, is seen so sharply, is presented so unforgivingly, that Network will outlive a lot of tidier movies.
Sidney Lumet’s direction is outstanding.
The Hollywood Reporter
Whatever its flaws, Network is a picture that can stand on its own. And does.
The New York Times
Network can be faulted both for going too far and not far enough, but it's also something that very few commercial films are these days. It's alive. This, I suspect, is the Lumet drive. It's also the wit of performers like Mr. Finch, Mr. Holden, and Miss Dunaway.
It's a dark, dark comedy that ruthlessly skewers the news industry on a stake, then roasts it alive.
TV Guide Magazine
There's an amazing display of acting talent, even though director Lumet doesn't quite tie all the strands together.
There is a lunatic energy about it. Every once in a while, Chayefsky abandons the struggle to dramatize his ideas and has somebody, usually Holden, just turn to the camera and spout off. In those moments, his concern — and sometimes his mother wit — comes blazing through and the picture takes on a life not found in safe, sane, well-calculated movies.
